Answer:
She should use a thermoflask instead of a measuring cup
Step-by-step explanation:
Jennifer is working in hot kitchen and if she use a liquid measuring cup to keep water and ice inside it then it is wrong because after sometime the water and ice will become warm with the heat present inside the hot kitchen and she will again fetch ice and water after a short period of time. If she use a thermos instead of a liquid measuring cup then that would be beneficial because thermos will allow her to keep the ice and water cold for a long period of time.
